First of all, we should not be so surprised if G*d appears to a scientist more like a Super-Scientific working hypothesis than the Suffering Servant from Second Isaiah.
Plank was not the only scientist to feel that way.
Second, there are circa two billion Christians in around 40,000 denomination spread amongst five general groups, and none teaching precisely all the same doctrines.
So you have to allow for some slack in doctrinal uniformity amongst different denominations.
Finally, here is a summary of Max Plank:
"He won the 1918 Nobel Prize in Physics and is considered the founder of Quantum mechanics.
He had been raised an observant Lutheran and was an elder in his church from 1920 to his death (1947).
In 1937 he delivered the lecture, "Religion and Natural Science", stating that both religion and science require a belief in God."
So I'd say, if you are going to claim that an elder in a Lutheran Church is "not Christian" enough for you, then really that is a problem of your own making having little to do with reality as most people understand it, FRiend.
Finally, here is a summary of Max Plank:
“He won the 1918 Nobel Prize in Physics and is considered the founder of Quantum mechanics.
In the first place, God is not impressed by the things men are impressed by and second, it is not up to any man to decide if another man is Christian enough. God is the Judge of all such matters.
